The rails are connected by Vthe braces 18, 19

"and 20. -The brace 18, as Seen best inFig. l

of the drawings, extends across the full front edge of the` top rand servesr to support the Thelinks 25are operatively engaged with the bolts .f26fand serve; to retract the same ,lengthwise when the springs 27 .are` permitted to extend the links 25 and parts con- .neoted therewith to .the position shown in Fig. l of the drawings.

ANormally the links 25 and springs 27 are forced backward .by vthe drawer* 2l when the` same is inthe closed position indicated V,inlig 5 of theldrawings. As seen in said figure, when thellinks' 25 are forced back Ward they operate tospread the bolts26 for extending [the ends thereof through the eyelets28at the rear `of the drawers 22.

It is obvious that when the 'drawers 22 `and 21 are closed ingthe order named, the

first-mentioned [drawers cannot ,be withdrawn from their .recesses until the drawer 2l 1slirst,opened.` "This action is assisted by the st op pins29` which the ends of the The pins 29 prevent the nient of the" drawers 22.

" To' lock 'thegdrawer 21 inits closed position, is the office of the spring tongue 30, "ithej forwardA end of whih; isV free to Adrop behind an abutment 31 at the edge of the brace (18, as seen best in Fig. 9 of thedrawi mgs- Vdrawer 21` is closed, 'the tongue 30 is held f in engagement witlijthe abutment 31. ``-=beooi'ne's` necessary ,before said drawer can `Asshown 4in said digure, when the bedrawn fromits recess,- to disengage the tongue 30. To `this end, a spring 32 is dis- A,posed on jtlie lupperside of jthe `bottoni 33 of fthe recess for l-thefdrawer 21. The said yspring is `provided with a button 34 which extends through a perforation provided `in 'the said bottom 33 andiflush therewith. 'Usuallyjthe button 84 is tted Vcarefully to -the perforation Iprovidedfonit so that the button cannot-be readily detected by the fingers when moving under the bottom 33 the button 34.

When the owner or occupant of the desk presses upward the button 34, he lifts the free end of the tongue 30 from engagement with the abutment 3l. While the spring 1s thus lifted, the drawer 21 may be pulled from its recess and the springs 27 liberated to rock the links 25 and bolts 26 connected therewith so that the ends of the bolts are withdrawn from the eyelets 28.

From the .above it is obvious that the drawer 2l operates as a master locking device for the drawers 22.

Each of the drawers 22 serves as a locking device for one of the cabinets 35. Each cabinet 35 is provided with a false front 36, which is paneled and provided with drawer knobs 37 in imitation of the drawers with which a desk is usually furnished. Fach cabinet is pivotally mounted at the front 'inner corner thereof on friction-reducing devices such as the bearing balls 3,8.I The balls 3S are mounted in races provided in the plates 39, one of which is in the bottom of "the cabinet 35 and the other in the bottoni 40 of the pedestal wherein the cabinet is mounted.

As seen best in Figs. l to 3, inclusive, the cabinets 35 have pigeon-holes 4l and drawers 42 opening from one side of the cabinet, or the outer panels of the pedestals when the cabinets are in closed position. When the cabinets are swung on their pivots outwardly, the openings of the said pigeonholes and drawers are turned to the outer side and in surrounding relation to the well of the desk or leg space between the pedestals. closed position by pins 43, as shown best in Fig. 6. The pins 43 are mounted at the ends of springs 44 and beneath the cam ends 45. The ends 45 are so shaped and arranged that when the drawers 22 are forced inward, theyk override said cam ends and force the same downward until the pins 43 extend through perforations y46 in the tops of said cabinets. It is obvious that in this position the cabinets 35 cannot be rotated on their bearings and on the pivot threaded ends of these bolts are passed` through perforations 49 in ianges 50 eX- tpended inwardly from the outei` panel of said pedestals. e

.When the cabinets 35 are closed, the nuts Normally the cabinets are locked inv y l] ositio n the freeend p vbehind the abutment 31 and eectiveflyl locks the drawer 21', preventing the opening "thereof. In this position, unless the personjdesirto open the desk is aware of the location which engage the bolts 48 below the said flanges are coveredk and protected from being interfered with. Therefore, an unauthorized person cannot gain access to the interior of the desk by separating the elements thereof. i From the foregoing it will be seen that themas'terelement for releasing the drawers and cabinets of the desk and for giving access to the bolts 48, fis tofbe found in the button 34. Asabove stated, the button 34 is so shaped that itl neatly lits the' perforation provided for it in the bottom"33 of the desk top. i The above indicated portion of the desk is normally invisible, and thelocation of the button would be indicated only, to the owner or one having full knowledge of the construction.` Further, it will be observed that p thelocation bf the button 34 and the perforation' for holding the`l` same might be varied to suit the taste of different owners.`

When desiring to close the desk, the drawers 42 in the cabinets 35 if previously opened are closed.` lThe cabinets 35 'are then swung "on their bearings 38 and pins' 45 from the position shown at the left of Fig. l of the drawings to the position shown at the right of said figure. The drawers 22 are opened to permit the cabinetsto swing inward past the pins`43, which ar'eraised normali' by the springs 44 out of the path of said cabinets.

When the cabinets are in position, the drawers 22 are closed, thereby epressing thefree end of the 'springs I44` and pins 43 connected therewith causing the flatter toV extend to lock the same against rotation`.'

4throughthe perforations 46 in thecabinets "Prior to Vclosing the drawers 22A V,it is neces# sary to partially'open'the 'drawer 21 so that the bolts 26 maybe retracted from the path ofthe eyelets 28j` When the said Adrawers 22 havebeen closed,the drawer 2l is'pressed inward against the links 25 to extend the bolts 26, causing 'thefreeends thereof to enter said eyelets. `Whenthe drawer 21ha's 'been completely closed, the free endofthespring 30 loverrides lthe spring `32, 'depressing the same until the face of A`the button 34 is flush, with the lower surface of` the ybottom 33. this of thef spring T30 'falls `cabinets 35,'effecft a further mystification to one Aunacquaiiited` withthe y'structure for if the drawers 21` and 22 are operated, `the intruderismore apt to,- endeavor to gainfaccess ,i to the cabinets '35 by pulling` on the' lniobs 37 of theapparent drawer with which'they'see'm 130 Laeaaae to be connected. Pulling on the knobs 37 operates to more effectively close the cabinet, thus defeating the purpose of the unauthorized operator.
